Barcelona, Mobile World Congress, Feb. 25, 2013–SPIRIT DSP, the world’s #1 voice and video over IP engines provider serving more than 1 billion users in 100+ countries, today announced a new version of its VVoIP software SDK (Software Development Kit), TeamSpirit® Voice&Video Engine Mobile 4.0, that provides interactive mobile HD voice and video calls in RCS (Rich Communication Suite). TeamSpirit Voice&Video Engine Mobile 4.0 is compliant with the RCS 5.1 specification, the last version of the GSMA-driven standard for carriers’ IP services, which allows telcos together with developers to quickly bring high-quality IMS voice and video calling functionality to their RCS-compliant services, applications and devices. The new engine is also fully compatible with standard SIP, IMS and VoLTE specifications.

TeamSpirit Voice&Video Engine, encompassing the new RCS communication standard, provides telcos with an easy-to-use SDK to create rich HD voice and video applications and bring them to market in record time, allowing them to remain more competitive and keep subscribers satisfied by responding more rapidly to their expectations for high quality voice and video calling on LTE networks. SPIRIT customers, such as BroadSoft, Huawei, KT, LG U+, Maaii and Reliance have developed or are now developing RCS applications and services using TeamSpirit Voice&Video Engines.

An approved by the International Telecommunication Union (ITU) standard, the RCS 5.1 specification aims to provide fully interoperable and standards-based rich functionality to end users, such as IM, presence, sharing, as well as voice and video over IP calls. The specification allows telecom operators to effectively compete with innovative and agile OTT (Over-The-Top) service providers, retain and even expand their subscriber base with high-quality, feature-rich, standards-based mobile applications available across a wide set of handsets and mobile networks.

“It is not only cross-platform messaging services that are killing telcos SMS traffic. Without HD voice and video over IP as a part of carriers’ RCS offering, irreparable loss of voice revenues is the challenge telcos have to deal with right now”, said SPIRIT’s Chairman Andrew Sviridenko. “TeamSpirit Voice&Video Engine Mobile has been recognized by carriers around the world as an effective way to remain more competitive with OTT, bring richer RCS calls to their subscribers, enhance the value of LTE networks and keep their subscribers connected.”

TeamSpirit Voice&Video Engines support both RCS and VoLTE. The engines include resource-efficient HD voice and video codecs, echo and noise cancelling (AEC), automatic voice and video rate selection (ARS), packets delays mitigation, speech enhancement, network adaptation, voice and video synchronization, a dozen of standard digital telephony functions and more. In addition to a dozen of ITU-T standard G.7xx and H.26x codecs included in the engine, SPIRIT also offers its own industry leading patented IP-MR™ (IETF RFC 6262) adaptive and error-resilient HD voice codec that has been selected by Tier1 telecom operators to deliver HD voice to dozens of millions of their subscribers. TeamSpirit uses H.264SVC and VP8 video codecs. TeamSpirit Voice&Video Conferencing Engine is an additional server-side module bringing all the power of TeamSpirit’s robust high-quality calling to centralized multi-point communication scenarios.

TeamSpirit Conferencing powers SPIRIT’s VideoMostTM software for massively multipoint videoconferencing. SPIRIT video engines are available on Windows, Mac, iOS, Android and allow users of smartphones, tablets and notebooks across different OSs to make video calls from iPhone to Android smartphones to PC, as well as participate in HD videoconferencing with automatic quality adaptation to specific network conditions, screen size and processing power.
